ABSTRACT
Objective To analyze the risk factors of post-operative respiratory failure in elderly cardiac carcinoma patients.Methods 28 elderly patients with respiratory failure (respiratory failure group) after the resection of cardiac carcinoma and 56 controls (control group) were studied.Preoperative respiratory function,the other complications,the site of incision,intravenous infusion,age of patients and smoking between two groups were compared by Logistic regression.Results Univariate risk factors included MVV<50% ,RV/TLC>50% ,FEV1<1.5L,PEF<70% ,DLCO<80% ,V75<70% ,the venous input,incision at chest.Multivariate logistic regression analysis identified that MVV<50% ,RV/TLC>50% ,FEV,<1.5 L,DLCO<80% were risk factors.Conclusion These results suggested that the patients with risk factors described above need more careful pre and post operative surveillance and management.
